Figure 7 in Food storage and morphological divergence between worker and soldier castes in a subterranean myrmicine ant, Carebara perpusilla

Figure 7. Micro-CT comparison of replete worker and soldier (scaled) showing how the crop (blue asterisk) occupies most of the abdomen: 60% in workers, 92% in soldiers (calculated from three perpendicular axes). The crop of the soldier (0.306 mm3) is 25 times larger than the crop of the worker (0.012 mm3). Notice how the midgut is squeezed against the exoskeleton by the crop. See figure 8A for a non-replete soldier crop. Pictures were obtained with Drishti and show a superposition of 20 slices.
